    This software provides support for the <i>Tag Image File Format</i> (TIFF),
    a widely used format for storing image data.  The latest version of
    the TIFF specification is <a href="document.html">available on-line</a>
    in several different formats.
  </p>
  <p>
    Included in this software distribution is a library, libtiff, for
    reading and writing TIFF, a small collection of tools for doing
    simple manipulations of TIFF images, and documentation on the
    library and tools.  Libtiff is a portable software, it was built
    and tested on various systems: UNIX flavors (Linux, BSD, Solaris,
    MacOS X), Windows, and OpenVMS.  It should be possible to port
    libtiff and additional tools on other OSes.
  </p>
  <p>
    The library, along with associated tool programs, should handle most of
    your needs for reading and writing TIFF images on 32- and 64-bit
    machines.
  </p>
  <p>
    The software was originally authored and maintained by Sam Leffler
    but has been maintained by a cast of others since 1999.
  </p>
  <p>
    Questions should be sent to the TIFF mailing list:
    <a href="mailto:tiff@lists.osgeo.org">tiff@lists.osgeo.org</a>, with
    a subscription interface at
    <a href="http://lists.osgeo.org/mailman/listinfo/tiff">http://lists.osgeo.org/mailman/listinfo/tiff</a>.
